Waking Life is a very unusual animation movie created in a unique style and full of almost random philosophical dialogues that leave you with a lasting impression which is hard to describe. I can say with a high degree of certainty that most of you'll feel dizzy while watching it, and I don’t have the slightest idea whether you'll like it or not. Nevertheless, I highly recommend it to you because it's not just a movie — it's an experience worth its while. The film captivates you, and if you want to experience it to the fullest, I would recommend you watch it on a large screen, or better, in a cinema, a projector, or VR. Give it a try and let me know how you feel about it.
I don't want to write a lot to not spoil it for you; therefore, I'll end with a quote from the movie: "So you have these serotonic neurons that inhibit hallucinations that they themselves are inhibited during REM sleep. See this allows dreams to appear real, while preventing competition from other perceptual processes. This is why dreams are mistaken for reality. To the functional system of neural activity that creates our world, there is no difference between dreaming a perception and an action, and actually the waking perception and action."
